` To all whom it may concern z jointly invented a -new and usefulDevice.

Beit known that we, BARN'r'r Gnnsno-` virz and HARRY AxELRoD, subjectsof vthe Czar of Russia, residing at Canton, in the county of Stark andState of Ohio`,1fhave i for Extracting Spokes,` of which 'the following`is a specification. 4 o i j Our invention relates to a device forhex-i`tracting spokes and` `is` more specicallyy a` manually operated devicefor removing old,

worn or damaged spokes from wheel hubs when itis necessary to replacethe same with new spokes.

VThe object of our invention isto provide if: a simple, durable andeasily operated device for `removingspokes from wagon wheels.

i. A further objectV is to provide a device of this character.` which`maybe easily and readily adjusted to any size of wheel or spoke.

l With these objects in view the invention consists in the novelconstruction and ari rangementV of parts, hereinafterdescribed`lillustrated in the accompanying "drawings,

andparticularly pointed out inthe append-` yed lclaims, it beingunderstood that various changes inthe form,- proportion, size and minordetailsgofl construction may be lmade within the scope l,of the appendedclaims without departing from the spiriti or sacri- 1 cingA any offftheadvantagesof the inven- In the corresponding parts throughout theseveral.,

of a wheel, Fig. v1 of the drawingsshowing theffeet on the hub A shownin dotted lines. Ata point near the feet 6 Aan arched tiesba'. Sconnectsthe two legs 2 and isv attached theretoby means of rivets 9, a similartiebar 10 being located `opposite thetie-bar 8 `and connecting the twoVguide plates 4, be-v ingattached thereto by means or their equivalents.Y n v VA `screw threaded stem 12 1is located .through the internallythreaded aperture 13 in the block 1 andis provided lat its outerextremity `with a suitable hand wheel 14 which is rigidly connectedthereto by any suitable `andwell,known meanssuch as the of ,rivets 1,1,j

set screw 15. The inner extremity of the:

stem 12 isreduced at 16 and is rotatably mounted within the aperturel?.located in the head` 18 of the slidingjaws,3a collar 19 being placedupon the reducedportion 16 and` attached thereby bymeans of a pin 20.`

The jaws 21 and 22 which. areadapted to grip the spoke ,are pivoted tothe head 18 by means Vont 'bolts 23 ,and 24, respectively,said jawsbeingprovided'at their free extremities with teeth 25. i Teeth 26 mayalso be provided upon the jaws at a point intermef diate their ends. Astirrup 27 is located around the jaws 21 and 22 and provided with acentral arched portion 28. One extremity `of the stirrupis reduced at29, and

`adapted to slide uponfonc of the legs 2 and is provided withapertures30 through which c a bolt` 31 is passed, said bolt connecting thestirrup to the jaw 21 bymeans of the eye 32 in saidjaw, theoppositeextremity 33 l,of

thek stirrup beingA squared and slidably mounted between theopposite legv2 andthe guide plate 4 and provided withaninternally screw threadedaperture 34. A curved leaf `*spring 35 is connected to theV jaw 21 bymeansot rivets 36 and has its free end resting upon the jaw 21, saidspring contacting with the adjacent leg 2 intermediate its ends,

tending to hold the jaw 21 in contact with the spoke B shown in dottedlines Fig. 1; a U-shaped spring 37 is `also attached to the jaw 21 bymeans of the rivets 36 and its free endcontacting with the inner face ofthe i jaw 22 tending to hold the two jaws apart. Suitable guide flanges38 are provided upon the outer face of the` jaw 22 for the purpose ofmaintainingthe stirrup 27 in `'alinement and a screw threaded stem 39 islocated through the internally threaded aperture 34 in the squareportion 33 .of the stirrup,the

inner 'extremity of the screw threaded stem Y contacting with thej aw22, a suitable .hand

wheel 40 being vprovided upon the uoi'lt'er-end' ff out ofthe socket inthe hub 1A.
